FLUOROSIS AND “BLACKS”
©1996-2016 PFPC

If fluorides are truly anti-thyroid agents then fluoride effects (i.e. “dental fluorosis”, thyroid dysfunction) should be observable more so in black then in white children - as blacks have a considerable lower "normal thyroid status" and thus effects would be more pronounced among the black population (e.g. Long et al, 1985; Schectman et al. 1991). Afro-Americans have lower normal TSH levels than whites (Hollowell et al., 2002), hence fluoride - being a TSH clone - would have more pronounced effects on this population.

In 1962 Russel reported on the progress in Grand Rapids, after 16 years of fluoridation. There was fluorosis in 19.3% in the white children, and 40.2 percent in the black children. In 1949 Hurme had also oberved more enamel opacities in the upper incisors of black children.

Of course this now has been observed many more times since (Butler, 1985; Duncan et al, 1988; Silberman et al, 1991; Kumar 1999; etc.)

"The prevalence rate of primary canine hypoplasia was 33.2% for black children and 17.2% for white children. These data indicate that this lesion is significantly more prevalent in blacks than whites, and that teeth with this lesion have a greater probability of developing dental caries."
